Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Chloro-3-(diethylamino)-1-((dimethylamino)(hydroxy)methyl)-2,4-dioxo-1,2,3,4-tetrahydroquinazoline-6-sulfonamide.
7-Chloro-3-(diethylamino)-1-((dimethylamino)(hydroxy)methyl)-2,4-dioxo-1,2,3,4-tetrahydroquinazoline-6-sulfonamide (CAS 87296-75-1) is a high-purity analytical reference standard with the molecular formula C15H22ClN5O5S and a molecular weight of 419.88 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 7-Chloro-3-(diethylamino)-1-((dimethylamino)(hydroxy)methyl)-2,4-dioxo-1,2,3,4-tetrahydroquinazoline-6-sulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 419.88 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
